+`CF_REDIRECT` is the same as `CF_TEMP_REDIRECT` but generates a
+http 301 redirect (permanent redirect) instead of a temporary
+redirect.
+
+These redirects are cached by browsers forever, usually ignoring
+any TTLs or other cache invalidation techniques.   It should be
+used with great care.  We suggest using a `CF_TEMP_REDIRECT`
+initially, then changing to a `CF_REDIRECT` only after sufficient
+time has elapsed to prove this is what you really want.
